This Project Grant award of $729,600 from the National Science Foundation's (NSF) Geosciences Program (CFDA 47.050) will support research to improve understanding of megathrust faulting and subduction zone hazards. The University of Oklahoma, the awardee, will develop new computational tools that combine real-world geophysical observations and physics-based models to study major earthquakes in Chile, Japan, and Alaska over the past 20 years. The research aims to illuminate fault stress and strength heterogeneity, and factors controlling subduction zone seismogenesis, to generate physics-based estimates for plausible hazard scenarios and probabilistic forecasts of deformation and aftershocks for selected high-risk subduction zones. This integrated project will advance fundamental understanding and public awareness of these complex tectonic processes through coordinated research and educational efforts, including partnerships with local organizations and teachers to develop community-oriented learning materials. The award period is from July 1, 2025 to June 30, 2030.
